Is there a reason why udev sets the permissions and SELinux context every=

time it finds an existing node or symlink?

The code in question is (from udev_node.c):

in udev_node_mknod():
if ((stats.st_mode & S_IFMT) =3D=3D (mode & S_IFMT) && (stats.st_rdev =3D=
=3D devt)) {
	info("preserve file '%s', because it has correct dev_t", file);
	selinux_setfilecon(file, udev->dev->kernel, stats.st_mode);
	goto perms;
}

in node_symlink():
if (strcmp(target, buf) =3D=3D 0) {
	info("preserve already existing symlink '%s' to '%s'", slink, target);
	selinux_setfilecon(slink, NULL, S_IFLNK);
	goto exit;
}
